I’m writing a book for the popular “For Dummies” brand by Wiley, Twitter Application Development for Dummies, #TADD for short.
While doing research for the book I compiled a brief timeline of Twitter’s company history. I was about to remove it from my notes when I realized it was kind of interesting, and I might like to refer to it later. So, I’m throwing it up on the blog for you to enjoy.
